From: Baltic Sea methanogens compete with acetogens for electrons from metallic iron
Modeled competitive interaction between Fe0-corroding acetogens and Fe0-corroding methanogens. (1)— indicates a possible direct mechanism of electron uptake, (2)—indicates a mechanism of electron uptake based on abiotic-H2 and (3)—indicates extracellular enzyme-mediated H2-evolution
